Extends [Purchase Header Archive](../table/5109.md).

## Fields

Explanation: the field's ToolTip in the code; without one, the ToolTip of a page control bound to the field (marked via the page); without that, its Caption (marked caption) when that differs from the name.

| No. | Name | Type | Explanation | Notes |
|---|---|---|---|---|
| 20520 | Subc. Location Code | Code[10] | Subcontracting Location Code <small>caption</small> | TableRelation [Table 14 "Location"](../table/14.md) (Location where("Use As In-Transit" = const(false))); DataClassification CustomerContent |
| 20521 | Subc. Order | Boolean | Subcontracting Order <small>caption</small> | FlowField: exist("Purchase Line" where("Document Type" = const(Order), "Document No." = field("No."), "Prod. Order No." = filter(<> ''), "Prod. Order Line No." = filter(<> 0))); not editable |

## Relations

- Subc. Location Code: TableRelation [Table 14 "Location"](../table/14.md)
- Subc. Order: CalcFormula [Table 39 "Purchase Line"](../table/39.md)
- extends [Table 5109 "Purchase Header Archive"](../table/5109.md)

## Recent changes

- 2026-08-18 [#9892 [main] Bug 644283: Renumber Subcontracting app object ids as it clashes with partner range](../../changes/bcapps/9892.md) (main, BC30, refactor)

## Across versions

- Present in: BC29-30
- Changed (declaration) in: none

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## Ask your agent

Procedure bodies are not stored here (D10). For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "tableextension", object_name: "Subc. Purchase Header Arch")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
